ARBOR-PRESS.

Specification of Letters Patent.

Patented Feb. 9, 1915,

Application filed January 2, 1914. Serial No. 809,883.

To all whom it may concern:

Be it known that I, JOHN B. FLINT, a citizen of the United States,residing at Boston, in the county of Sufiolk and State of Massachusetts,have invented new and useful Improvements in Arbor-Presses, of which thefollowing is a specification.

This invention relates to improvements in arbor presses and has for itsobject to provide a simple and easily operated arbor press which will becapable of receiving and positioning a large variety of arbors, as todifferent diameters thereof, and a large variety of sizes and shapes ofpieces into which the arbors are to be forced. In order to position thislarge variety of arbors and pieces of work into which they are to beforced, or from which they are to be removed, I employ a plate uponwhich the work directly rests and this plate, which may be termed asupplementary workplate or support rests upon a stationary work-supporthaving a notch therein.

The supplementary work-support is provided with a V-shaped slotextending thereinto from the front edge thereof so that a large varietyof diameters of arbors may be accommodated by said V-shaped slot whilethe pieces into which these arbors are forced, or from which they are tobe forced are securely supported and rest upon the supplementaryworksupport in which said V-shaped slot is provided. In addition to thesupplementary work-support being provided with a V-shaped slot, thiswork-support has its efliciency greatly augmented by being transverselymovable upon the stationary work-support of the arbor pressthat is, thesupplementary work-support can be moved forward and back or sidewise orat any angle so as to bring the V-shaped slot at any desired positionrelatively to the plunger of the press, and by this combination of thesupplementary work-support with the v-shaped slot and by the capabilityof moving this supplementary work-support to any desired positionrelatively to the plunger of the press I obtain a press capable oftaking practically all sizes of arbors, from large to small, within theextreme capacity of the arbor press employed.

The supplementary work-support hereinbefore referred to is so attachedto the press that the same may be quickly positioned and still at thesame time its movement may be limited, and furthermore the same is so attached to the press that while the supplementary work-support isuniversally slidable upon the bed of the press it is not detachabletherefrom and will always be found 1n convenient position to be adjustedrelatively to the plunger of the press to receive the work.

In addition to the V-shaped slot in the front of the supplementarywork-support,,I also provide a series of holes of different diameterswhich are to be used in cases where it is desirable to support the Workinto which the arbor is to be pressed or from which it is to be removedclose to said arbor and entirely therearound, and these holes arepreferably arranged in such manner that they may be quickly positionedrelatively to the plunger of the press, this positioning being obtainedby sliding the supplementary work-support forwardly or backwardly, asthe case may be, beneath the plunger, the operator being assisted inthis positioning operation by the specific construction hereinafterclearly set forth in this specification.

The invention consists in the combination and arrangement of parts setforth in the following specification and particularly pointed out in theclaims thereof.

Referring to the drawings: Figure 1 is a side elevation, partly insection, of an arbor press embodying my invention. Fig. 2

is a sectional plan taken on line 2-2 of Fig. 1, with the supplementarywork-support or plate shown in two positions, one of said positionsbeing illustrated by dotted lines.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 4 is the frame of an arbor press, the same beingprovided with a work-support 5 notched at 6 to receive the ends ofarbors which are to 'be forced through work placed on said work-support.A plunger 7 of the usual type, is reciprocatorily arranged in a bearing8 in said frame 4: and adapted to be reciprocated by a pinion 9 engagingteeth 10 on said plunger and a hand lever 11 connected with said pinionto rotate the same.

The plunger 7 is arranged to be reciprocated at right angles to thesurface of the wor -support 5 for the purpose of forcing arbors ormandrels from or into the work. A supplementary work-support or plate 12is mounted on and movable transversely of said work-support 5, saidplate being preferably formed of two layers of material 13 and 1a, thelower layer 1 1 being preferably formed of material such as cast iron,while the upper layer 13 is formed of relatively harder material, suchas steel, and is prefe erably hardened to prevent chipping or wearcaused by contact with the work into which the arbors are forced, saidlayer 13 being secured to the portion 14 by screws 15.

The layer 13 is formed in two parts for convenience in manufacture andis preferably joined along the line 16. The plate 12 has a V-shaped slot17 extending there through from top to bottom and opening at the frontedge 18 of said plate and is adapted to be adjusted to fit various sizesof man drels alining with the plunger 7, said V- shaped slot beingemployed when it is de sired to force a mandrel or arbor from a piece ofwork which is of such a thickness that it does not require a supportentirely around said arbor. This, however, would not always be the case,as it is often necessary to force arbors or mandrels into work of such athickness that the support must entirely surround and fit said mandrel;otherwise said work would be bent or in jured by the pressure appliedthereto. For this purpose the plate 12 has been provided with aplurality of holes 19 extending laterally through said plate, each ofwhich is of a different diameter, thus adapting said plate tosubstantially all sizes of arbors, said holes being arranged in such amanner about said plate that they may be severally brought intoalinement with the plunger 7. It will, however, be observed that saidholes 19 are arranged at a suilicient distance from the edge of the\l-shaped slot 17 and the sides 20 of said plate in order that saidplate will extend completely across and rest upon each said of the notch6 in the worksupport 5, whereby said plate will be supportedsimultaneously upon opposite sides of each of the holes 19.

It is essential that the plate 12 be permitted to move freely on saidwork-support 5 in substantially all transverse directions, that is, bothtransversely and longitudinally of said plate, in order that the holes19 may be quickly moved into alinement with said plunger, and a handle21 has been pro-- vided to facilitate the adjustment thereof. Inaddition to the desirability of having the plate 12 move freely on thework-support 5 in substantially all transverse directions, it is alsodesirable that said plate should be at all times connected to the frameof the press in such a manner that it will be in position for theoperator to employ and will not be liable to become detached therefromand lost. To accomplish this result an arm 22, preferably consisting ofa rod, extends from the rear of the plate 12 through an opening 23 inthe front wall of the frame eland into a recess 24 formed in said frame.A stud 25 is adapted to slidably engage said rod 22 and has acylindrical stem 26 projecting upwardly therefrom and pivotally engagingthe frame 4, permitting said plate to be moved on the work-support 5substantially in all directions transversely thereof, but preventing theupward movement of said plate relatively to said work-support.

The movement of the plate 12 is suflicient to permit any one of theholes 19 and the slot 17 to be placed in alinement with the plunger 7,but beyond this said plate is prevented frombeing moved by the ends ofthe opening 23 against which said arm 22 is adapted to strike, while ascrew 27 limits the outward longitudinal movement of the rod 22relatively to the stud 25.

It will be seen that the holes 19 are arranged in two series 28 and 29upon opposite sides of the V-shaped slot 17, each of said series beingradially disposed relatively to the cylindrical portion 26 of the stud25. Thus when the arm 22 is. at the end 30 of the opening 23, as shownin dotted lines, the forward and rear movements of said plate will causethe holes in said series 28 to substantially aline with the plunger 7providing said arm is kept in contact with said end of said slot, andshould the plate 12 be moved transversely of said work-support untilsaid arm 22 is at the end 31 of the opening 23, the series of holes 29may likewise be successively alined with said plunger by the forward andrear movement of said plate.

In the operation of the device the plate 12 is adjusted or moved until ahole of the proper diameter or the portion of the slot 17, whichcorresponds to the diameter of the mandrel or arbor which is to beforced into or removed from the work, is brought into alinement with theplunger 7, after which. the handle 11 is revolvedto move said plungerdown against the arbor to force the same through the work-supported bysaid plate, as illustrated in Fig. 1'.
